Installed at a diagonal in David Zwirner Gallery’s huge ground floor 20th Street space, late artist Richard Serra’s 2015 sculpture ‘Every Which Way’ forces a decision from entering visitors who must opt to turn right, left or wind their way between the 16 steel panels. Regardless of how it is approached, the piece invites interaction and a physical comparison between a visitor’s body and the giant, weighty slabs of metal seven, nine or eleven feet tall that Serra likened to architecture. Unlike Serra’s rolled steel sculptures with their curving walls and warm, brown patina, this piece’s abrupt flatness and grey steel surfaces convey austerity. Their arrangement in shorter segments, however, gives visitors agency to explore this minimal but engaging arrangement of form. (On view through Dec 14th).
